Query Selection  Annotators search and annotate chains of entities connected by KBP slots Cold Start queries comprised of Entity TAC KBP Evaluation Workshop – NIST, November 18-19, 2013 Appleton Museum of Art org:top_members_employees John Lofgren per:title director

Query Selection  Annotators search and annotate chains of entities connected by KBP slots Cold Start queries comprised of Entity – Slot 0 TAC KBP Evaluation Workshop – NIST, November 18-19, 2013 Appleton Museum of Art org:top_members_employees John Lofgren per:title director

Query Selection  Annotators search and annotate chains of entities connected by KBP slots Cold Start queries comprised of Entity – Slot 0 – Slot 1 Inverse slots to increase connectivity e.g. per:cities_of_residence – gpe:residents_of_city TAC KBP Evaluation Workshop – NIST, November 18-19, 2013 Appleton Museum of Art org:top_members_employees John Lofgren per:title director

Query Selection  Annotators search and annotate chains of entities connected by KBP slots Cold Start queries comprised of Entity – Slot 0 – Slot 1 Inverse slots to increase connectivity e.g. org:founded_by – {per,org,gpe}:organizations_founded TAC KBP Evaluation Workshop – NIST, November 18-19, 2013 Appleton Museum of Art org:top_members_employees John Lofgren per:title director

Annotation  Unlike other SF tasks, Cold Start annotation is performed concurrently with query development  Multiple fillers at each “hop” level, all of which must be annotated and correctly connected to one another TAC KBP Evaluation Workshop – NIST, November 18-19, 2013 London – gpe:residents_of_city – per:charges Lance Barrett first-degree attempted burglary theft of a firearm carrying a concealed weapon Lesa Bailey criminal conspiracy to make meth unlawful possession of meth precursors possession of a controlled substance

Assessment  Assess validity of fillers & justification from humans & systems Filler Correct – meets the slot requirements and supported in document Wrong – doesn’t meet slot requirements and/or not supported in doc Inexact – otherwise correct, but is incomplete, includes extraneous text, or is not the most informative string in the document Predicate Correct, Wrong, Inexact-Short, Inexact-Long Subject/Object Correct, Wrong, Inexact Ignore TAC KBP Evaluation Workshop – NIST, November 18-19, 2013

Justification  Justification is the string(s) of text that show a relation is true Predicate: Includes all three pieces of information necessary to justify the entity/slot/filler relation Subject: proves the entity’s involvement in the relation Object: proves the filler’s involvement in the relation Each part can be comprised of up to two, discontiguous strings Predicate 1: the Islamabad headquarters of Harkat-ul-Mujahideen Predicate 2: Islamabad, the capital city of Pakistan TAC KBP Evaluation Workshop – NIST, November 18-19, 2013 New in 2013: Ronnie James Dio - per:date_of_death: Sunday [ ]

2013 Discoveries  New justification scheme used in unexpected, creative ways Additional predicate strings used to disambiguate entities Predicate 1: Ginzburg died late Sunday of cardiac arrest. Predicate 2: Vitaly Ginzburg, a Nobel Prize-winning Russian physicist and one of the fathers of the Soviet hydrogen bomb TAC KBP Evaluation Workshop – NIST, November 18-19, 2013
